Toallwhomz'tmay concern:

Be it known that I, BRANDO MARGH, a' citizen of the United States, residing at Delmont, in the county of"`Westmoreland and State o f Pennsylvania, have invented new and useful Improvements in Pendant-Cord Switches, of which the following is a specification.

This invention relates to electrical devices, particularly to switches, and has for its object the provision of a novel switch designed primarily for use in connection with pendant cords used in connection with droplights or the like, the 'switch being of very simple construction and being easily operable whereby the current may be cut oilwhen so desired.

v'An important object is the provision of a switch of this character which entirely' eliminates the necessity for the em loyment of the ordinary switches and whic will be much neater in appearance as it may be made very small and attractive.

Andther object is the provision of a switch of this character in which the construction is so simple that repairs or replacement of a worn art may be easily made by even an unskilledJ person and Without the use of any elaborate tools.

An additional object is the provision of a switch of this character which will be very simple and inexpensive in manufacture, highly efficient in use, positive in action, diirable'in service and a general improvement in the art. y l

l/Vith the above and other objects and advantages in view, the invention consists in the details of construction, to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which: n

Figure 1 is a side elevation of the switch. Figure 2 is an elevationtaken at right angles to Figure 1.

iguie 3 is a longitudinal sectional view showing the switch in circuit breaking position. l

Figure 4 is a similar view showing the parts in circuit making or closing position.

Figure 5 is an end view.

Figure 6 is a cro sectional view.

Figure 7 is an elevation of one side ofthe body member.

Figure 8 is an elevation of the opposite side.

Referringmore particularly to the draw- 28 as shown.

ings, I have shown the device ing an elongated body 10 formed as a strip of insulating material upon the tion of one side of which is secured a metallic plate 11 which carries two binding screws 1`2 one of which is adapted for connection with a line wire 13 and the other end of which is adapted for connection with a wire 14. which leads to the drop light or other electric appliance.

Located upon the oppositeside of the body 10 neai the ends thereof are metallic plates 15 which are held in position by means of. screws 16 and which carry binding screws 17 oneof which is adapted for connection with a line wire 18 and the other of which leading to the drop light or other electric appliance to be energized. Formed at the side edges of the confronting ends, of the as compris-v central poris adapted for connection with a wire 19 The body member and associated parts together with the sleeve 24 is inclosed within a casing consisting of a Ashell member 26 which is provided at one end with a pair of holes 27 for the passage of the line wires 13v 'and 18 and which is provided near its other end with an elongatedslot 28 for the accommodatio'nror` the operating button 23 durin the movement thereof. One end of the shefi member 26 is formed with av reduced extension upon which is engaged a second shell member 29 which has one end closed and provided With a pair of holes 30 through which pass the wires 14 and 19 leading to the electric appliance. Thev opposite end of this shell member 29 is formed with a lug 30f which ts withinthe open end of the slot Assuming that the device has-been coni structed` and assembled as above described, when the switch is in normal or circuit breaking position, the operating button 23 is disposed at `one end of the slot 28 in'the shell .member and the sliding plate 21 is retracted from engagement with the overhan 'ng flanges on the most remote plate 15. en the parts are in this position, it -Will be seen that current cannot How from the line wires to the electric appliance. In order to close the circuit it .is merely necessary that the rom the foregoing description and a study of the drawing it will 'be apparent that I have thus provided a simply constructed and consequently inexpensive switch which is adapted for use in connection with drop lights, floor lamps, electric, table appliances and infact all such apparatus as is used in the household. Owing to the fact that all the working parts are entirely disposed within a shell of insulated material, it is apparent that this device may be operated with perfect safety and without any danger whatever of receivin a. shock. Another feature of advantage is t at the device will be extremely neat in appearance as it may be made very small. Owing to the simplicit of the construction and the fewness of t e parts it is apparent that there is nothing to get out of order and that the device should consequently have a long life and satisfactorily perform all the functions for which it is intended.

While I have shown and described the preferredembodiments of the invention, it

is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of invention or the scope of the subjoined claims.

Having thus described the invention, what is claimed is:

1. A switch of the character described comprising an elongated body of insulating material, a metallic plate secured upon one side of said body and carrying binding screwsya pair of metal plates secured upon the opposite side of the body and carrying binding screws, the inner ends of said pair of plates bei ng formed at their side edges with overhanging flan es constitutlng guides, a plate member s idably engaging navales said guides and havin an operating button, and an enclosin sections dispose in encircling relation to said body and the parts thereon and formed with a longitudinal slot for the accommodation of said button.

2. A 'switch of the character described comprising an elongated supporting body of insulating material, a `metal plate secured upon one side thereof and carrying binding screws, a air of metal plates secured upon the opposite sides` of said body in., spaced `end to end relation and carrying binding shel formed of separable screws, guide means at the inner ends of said pair of plates, a' slidable plate engaged within said guide means and adapted to brldge the space between` said pair of plates, a

'shank extending from said slidable plate and terminating in an operating button, an elongated tubular` sleeve engaged exteriorly upon said body and formed with a longitudinal slot opening out at one end for the accommodation of said shank, and an enclosing shell disposed in encircling relation to said sleeve and formed of separable sections, said shell beingiformed with a longitudinal slot for the accommodation of said button and havin its outer ends closed except for the provision of pairs of holes for the passage of wires to connect with said binding post or screws.

3. A Aswitch of the character described comprising an elongated body of insulating material, a metallic plate secured upon one side of said body and carrying binding screws, a pair of metallic plates secured upon the opposite side of the body and carrying binding screws, said pair of plates being formed at their adjacent ends with guides, a plate member havin an operating button and slidable within t e guides on oneplate and adapted to engage within the guides on the other one of said air of plates, and an enclosing shell for said bodyhaving a slot permitting operation of said button.

4. A switch of the character described comprising an elongated body of insulating material', a metallic plate secured upon one lside of said b ody and carrying means for connection with wires, a pair of metallic plates secured upon the opposite side of the body and provided with binding means for wires, the inner ends of said pair of plates being formed at their side edges with overhanging fian es constituting guides, a plate member slida ly engaged within said guides and having an operatlng button.

In testimony whereof I affix' my signature.
